Deep infiltrating endometriosis is the most severe form of the disease, defined by infiltration beneath the peritoneum greater than 5mm. It affects several anatomical locations including the bladder, the vesico-uterine cul-de-sac, the torus uterinum, the uterosacral ligament, rectovaginal septum and the colon-rectum. Deep infiltrating endometriosis is associated with infertility. Surgery performed for deep infiltrating endometriosis in the context of pain offers good pregnancy rates either spontaneously or after assisted reproductive technologies...

BACKGROUND: A paucity of data exists on the impact of transfer status on outcomes for patients undergoing non-emergency (urgent) colorectal surgery. This study characterized transferred patients undergoing urgent colorectal surgery and determined which patient comorbidities significantly contributed to poor outcomes. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database from 2012 to 2013 was used. Urgent direct admissions undergoing colon, rectum, or small bowel operations were compared to urgent transfers using bivariate and multivariable analysis models...

National and international guidelines recommend referring patients with severe forms of endometriosis to expert centers. However, there is a lack of clear criteria to define an expert center. We examined the roles of surgeon and hospital procedure volumes as determinants of morbidity in deep infiltrating endometriosis of the rectum and sigmoid colon (DIERS). METHODS: We conducted a French retrospective multicenter study of hospital facilities performing colorectal surgery for DIERS in 2015...

We examined the relationship between risk factors for surgical site infections(SSIs)and prognosis in 440 patients who underwent colon cancer surgery. We evaluated factors related to SSIs(GradeB II)and compared survival rates by stage. SSIs were observed in 36 patients. An increased SSI incidence was associated with pulmonary dysfunction, mGPS=2, CONUT≥2, PNI≤40, NLR>4.3, location(rectum), depth of tumor invasion(Bsubserosa, SS), lymph node metastasis, laparotomy, resection of other organs, colostomy, blood loss(large), and operative time(long)...

Osseous metaplasia (OM) is rarely observed in colorectal cancer (incidence < 0.4% in rectal cancer), where it has a non-specific clinical presentation and unknown pathogenesis. Here, we report three cases of colorectal carcinoma with OM and propose a new hypothesis. All three patients (two males and one female) were Chinese and had different sites of colorectal carcinoma with OM: rectum, sigmoid colon, and appendix. The pathologic diagnoses were serrated adenocarcinoma; moderately to poorly differentiated adenocarcinoma with micropapillary carcinoma and cribriform comedo-type adenocarcinoma; and mucinous adenocarcinoma, respectively...

To collect big data for further research to improve treatment outcomes in patients with colorectal liver metastasis (CRLM), the Joint Committee for Nationwide Survey on CRLM was established by the Japanese Society for Cancer of the Colon and Rectum and the Japanese Society of Hepato-Biliary-Pancreatic Surgery. The joint committee initiated data collection since 2014. The data of 4,237 patients newly diagnosed with CRLM between 2005 and 2007 were registered from 134 departments of 127 institutions (64%) among 209 departments (from 201 institutions) that agreed to participate in this study...

AIM: Both the Danish and NICE guidelines recommend prolonged thromboprophylaxis (PT) with low-molecular-weight heparin (LMWH) for 28 days postoperatively after elective surgery for colon cancer. The evidence relies on two RCTs that included not only colon cancers but also other abdominal cancers or benign colorectal diseases. Neither of those studies investigated the risk of venous thromboembolism (VTE) under Enhanced Recovery After Surgery (ERAS). We aim to describe the risk of VTE and estimate the cost of preventing one case of VTE by PT under ERAS...

REVIEW
Hiroaki Nozawa, Toshiaki Watanabe
Laparoscopic surgery has gained acceptance as a less invasive approach in the treatment of colon cancer. However, laparoscopic surgery for rectal cancer, particularly cancer of the lower rectum, is still challenging because of limited accessibility. Robotic surgery overcomes the limitations of laparoscopy associated with anatomy and offers certain advantages, including 3-D imaging, dexterity and ambidextrous capability, lack of tremors, motion scaling, and a short learning curve. Robotic rectal surgery has been reported to reduce conversion rates, particularly in low anterior resection, but it is associated with longer operative times than the conventional laparoscopic approach...

AIMS/INTRODUCTION: Gallstone sigmoid ileus is a rare condition that presents with symptoms of large bowel obstruction secondary to a gallstone impacted within the sigmoid colon. This arises because of three primary factors: cholelithiasis causing a cholecystoenteric fistula; a gallstone large enough to obstruct the bowel lumen; and narrowing of the bowel. We describe 3 patients treated in a district general hospital over a 3-year period, and discuss their management. METHODS: Cases were retrospectively analysed from a single center between 2015 and 2017 in line with the SCARE guidelines...

PURPOSE: Hand-assisted laparoscopic surgery (HALS) is a minimally invasive surgical technique with the combined benefits of laparoscopic surgery while allowing the use of the surgeon's hand for better tactile control. Obesity has been associated with higher conversion rates with multiport laparoscopic surgery, but not with HALS. This study aimed to examine the versatility of HALS in various clinical contexts. METHODS: All HALSs performed at 2 major tertiary centers in Sydney were prospectively collected for retrospective analysis...

BACKGROUND & AIMS: Malnutrition in patients with colorectal cancer contributes to increased postoperative complications. The aim of the study was to evaluate the prognostic value of several nutritional assessment parameters: body mass index versus percentage of weight loss grading system (BMI/%WL); Patient-Generated Subjective Global Assessment (PG-SGA); standardized phase angle (SPA) by BIA; muscle strength by handgrip strength; muscle mass by computerized tomography; and the combination of muscle mass and strength in patients undergoing resection surgery...

Rectal neuroendocrine tumor (NET) is a relatively rare lesion of the gastrointestinal tract, but the prospective examination with colonofiberoscopy or endoscopic ultrasound has increased the frequency of its detection. It is often difficult to determine the optimal treatment for NETs sized <20 mm in the clinical setting. Other clinicopathological variables are not considered in the current guidelines and staging systems. Although the effects of lymphovascular invasion are not covered by the World Health Organization (WHO) 2010 guidelines or tumor-node-metastasis (TNM) staging system, this may be promising for the establishment of improved guidelines and staging systems, particularly for early-stage colorectal carcinoids...
